I was still able to get in via ssh.</div><div>This seems to be correlated with memory problems.</div><div><br></div><div>I restarted LON-CAPA (loncontrol and httpd) on that machine and did the same on </div><div>my balancer, and it seemed to be fine.</div><div><br></div><div>Just about an hour ago I started having problems again. There seems to be a significant</div><div>increase in memory usage - the slope changed pretty dramatically as usage picked up.</div><div><br></div><div>While the machines are being used pretty steadily, I'm wondering if there's anything regarding</div><div>downloading of large pdf files or the like that may somehow be causing grief. They're not</div><div>working on homework as much as they are pouring over lecture notes.</div><div><br></div><div>I also found the lond.log file on my library to be huge (3Gb+?) last night. While there typically</div><div>isn't much in lond.log, and I have debug set to zero, I'm getting a bunch of messages like those shown</div><div>below. Is this a sign of poor communications between the machines developing under the load?</div><div>Is debug somehow getting turned on?</div><div><br></div><div>I'm at a bit of a loss for the behavior, and I definitely have some students pissed at me right</div><div>now.</div><div><br></div><div>Mark</div><div><br></div><div><br></div><div>============================================================</div><div><div>Tue Nov 15 05:26:57 2011 (21584): Command received: sethost, encoded = 0</div><div>Tue Nov 15 05:26:57 2011 (21584): Matched dispatch hash: mustencode: 0 ClientType 1Tue Nov 15 05:26:57 2011 (21584): Dispatching to handler sethost oucapa2</div><div>Tue Nov 15 05:26:57 2011 (21584): Request was sethost:oucapa2 Reply was ok</div><div>Tue Nov 15 05:26:57 2011 (21584): get_request: Request = ekey</div><div><br></div><div>Tue Nov 15 05:26:57 2011 (21584): Main: Got ekey</div><div>Tue Nov 15 05:26:57 2011 (21584): process_request: ekey</div><div><br></div><div>Tue Nov 15 05:26:57 2011 (21584): Command received: ekey, encoded = 0</div><div>Tue Nov 15 05:26:57 2011 (21584): Matched dispatch hash: mustencode: 0 ClientType 3Tue Nov 15 05:26:57 2011 (21584): Dispatching to handler ekey </div><div>Tue Nov 15 05:26:57 2011 (21584): Request was ekey: Reply was 7643ACBACEB8A7BAE8DBCE811563Tue Nov 15 05:26:57 2011 (21584): get_request: Request = sethost:oucapa2:put:ohiou:OUp200lib:nohist_resevaldata:author%2fmeap%2fcalculus%2fprecalcreview%2ftrig02%2dRadiansToDegrees%2eprobl</div><div>em___ohiou%2fOUp200lib%2fmath%2ftriangle_comp1%2eproblem___comefrom=1</div><div><br></div><div>Tue Nov 15 05:26:57 2011 (21584): Main: Got sethost:oucapa2:put:ohiou:OUp200lib:nohist_resevaldata:author%2fmeap%2fcalculus%2fprecalcreview%2ftrig02%2dRadiansToDegrees%2eproblem___ohiou%2f</div><div>OUp200lib%2fmath%2ftriangle_comp1%2eproblem___comefrom=1</div><div><br></div><div>Tue Nov 15 05:26:57 2011 (21584): process_request: put:ohiou:OUp200lib:nohist_resevaldata:author%2fmeap%2fcalculus%2fprecalcreview%2ftrig02%2dRadiansToDegrees%2eproblem___ohiou%2fOUp200lib</div><div>%2fmath%2ftriangle_comp1%2eproblem___comefrom=1</div><div><br></div><div>Tue Nov 15 05:26:57 2011 (21584): Command received: put, encoded = 0</div><div>Tue Nov 15 05:26:57 2011 (21584): Matched dispatch hash: mustencode: 0 ClientType 1</div><div>Tue Nov 15 05:26:57 2011 (21584): Dispatching to handler put ohiou:OUp200lib:nohist_resevaldata:author%2fmeap%2fcalculus%2fprecalcreview%2ftrig02%2dRadiansToDegrees%2eproblem___ohiou%2fOUp</div><div>200lib%2fmath%2ftriangle_comp1%2eproblem___comefrom=1</div><div>Tue Nov 15 05:26:57 2011 (21584): Request was put:ohiou:OUp200lib:nohist_resevaldata:author%2fmeap%2fcalculus%2fprecalcreview%2ftrig02%2dRadiansToDegrees%2eproblem___ohiou%2fOUp200lib%2fma</div><div>th%2ftriangle_comp1%2eproblem___comefrom=1 Reply was ok</div><div>Tue Nov 15 05:27:09 2011 (21508): get_request: Request = exit</div><div><br></div><div>Tue Nov 15 05:27:09 2011 (21508): Main: Got exit</div></div><div>========================================================================</div><div><br></div><div><br></div><div><br><div>
