We're running SOGo for a customer with 25k accounts. Occasionally sogod locks up and users cannot be served.
In such cases, the log below is from December, 15th 2011, sogod reports it has been hanging for a while: Dec 15 10:27:06 sogod [953]: [WARN] <0x0x1757e948[WOWatchDogChild]> pid 18602 has been hanging in the same request for 7 minutes Looking for the PID I get log like this: Dec 15 09:33:35 sogod [18602]: <0x0x177f6518[SOGoCache]> an error occurred when caching value for key '012345...@example.com +attributes': "CLIENT ERROR" Dec 15 09:33:35 sogod [18602]: SOGoRootPage successful login for user '012345...@example.com ' - expire = -1 grace = -1 Dec 15 09:33:35 sogod [18602]: <0x0x177f6518[SOGoCache]> an error occurred when caching value for key '012345...@example.com +attributes': "CLIENT ERROR" Dec 15 09:33:36 sogod [18602]: <0x0x177f6518[SOGoCache]> an error occurred when caching value for key '012345...@example.com +attributes': "CLIENT ERROR" Dec 15 09:33:36 sogod [18602]: <0x0x177f6518[SOGoCache]> an error occurred when caching value for key '012345...@example.com +attributes': "CLIENT ERROR" Dec 15 09:33:36 sogod [18602]: <0x0x177f6518[SOGoCache]> an error occurred when caching value for key '012345...@example.com +attributes': "CLIENT ERROR" Dec 15 09:33:36 sogod [18602]: <0x0x177f6518[SOGoCache]> an error occurred when caching value for key '012345...@example.com +attributes': "CLIENT ERROR" Dec 15 09:33:37 sogod [18602]: <0x0x177f6518[SOGoCache]> an error occurred when caching value for key '012345...@example.com +attributes': "CLIENT ERROR" Dec 15 09:33:37 sogod [18602]: <0x0x177f6518[SOGoCache]> an error occurred when caching value for key '012345...@example.com +attributes': "CLIENT ERROR" Dec 15 09:33:37 sogod [18602]: <0x0x177f6518[SOGoCache]> an error occurred when caching value for key '012345...@example.com +attributes': "CLIENT ERROR" Dec 15 09:33:37 sogod [18602]: <0x0x177f6518[SOGoCache]> an error occurred when caching value for key '012345...@example.com +attributes': "CLIENT ERROR" Dec 15 09:33:38 sogod [18602]: [WARN] <0x0x1a25f338[UIxEnvelopeAddressFormatter]> unexpected envelope address: <0x0x1a6b37b8[NGImap4EnvelopeAddress]: mailbox='' host='MISSING_DOMAIN'> Dec 15 09:33:39 sogod [18602]: [WARN] <0x0x1a25f338[UIxEnvelopeAddressFormatter]> unexpected envelope address: <0x0x1a434df8[NGImap4EnvelopeAddress]:> Dec 15 09:33:43 sogod [18602]: <0x0x177f6518[SOGoCache]> an error occurred when caching value for key '012345...@example.com +attributes': "CLIENT ERROR" Dec 15 09:33:43 sogod [18602]: <0x0x177f6518[SOGoCache]> an error occurred when caching value for key '012345...@example.com +attributes': "CLIENT ERROR" Dec 15 09:33:43 sogod [18602]: <0x0x177f6518[SOGoCache]> an error occurred when caching value for key '012345...@example.com +attributes': "CLIENT ERROR" Dec 15 09:33:43 sogod [18602]: <0x0x177f6518[SOGoCache]> an error occurred when caching value for key '012345...@example.com +attributes': "CLIENT ERROR" Dec 15 09:33:44 sogod [18602]: <0x0x177f6518[SOGoCache]> an error occurred when caching value for key '012345...@example.com +attributes': "CLIENT ERROR" Dec 15 09:33:44 sogod [18602]: <0x0x177f6518[SOGoCache]> an error occurred when caching value for key '012345...@example.com +attributes': "CLIENT ERROR" Dec 15 09:33:44 sogod [18602]: <0x0x177f6518[SOGoCache]> an error occurred when caching value for key '012345...@example.com +attributes': "CLIENT ERROR" Dec 15 09:33:44 sogod [18602]: <0x0x177f6518[SOGoCache]> an error occurred when caching value for key '012345...@example.com +attributes': "CLIENT ERROR" Dec 15 09:33:48 sogod [18602]: [ERROR] <0x0x19254068[UIxMailRenderingContext]> found no viewer for MIME type: application/msword Dec 15 09:33:50 sogod [18602]: [ERROR] <0x0x186fd538[UIxMailRenderingContext]> found no viewer for MIME type: application/msword Dec 15 09:33:51 sogod [18602]: [WARN] <0x0x1a6a5618[UIxEnvelopeAddressFormatter]> unexpected envelope address: <0x0x1a6c4718[NGImap4EnvelopeAddress]: mailbox='' host='MISSING_DOMAIN'> Dec 15 09:33:51 sogod [18602]: [WARN] <0x0x1a6a5618[UIxEnvelopeAddressFormatter]> unexpected envelope address: <0x0x19cb7598[NGImap4EnvelopeAddress]:> Dec 15 09:33:51 sogod [18602]: [WARN] <0x0x1a6a5618[UIxEnvelopeAddressFormatter]> unexpected envelope address: <0x0x1a6a1158[NGImap4EnvelopeAddress]: mailbox='' host='MISSING_DOMAIN'> The system is: - RHEL 5.7 - sogo-1.3.10-1-el5 - memcached-1.4.5-1-el5.rf - libmemcached-0.34-1 My first idea and blind guess was that memory size for memcache was too small. Increasing memcache memory seems to have helped a bit, but still sogod locks up. What can I do to find out what causes the error? thanks p@rick -- state of mind () Digitale Kommunikation http://www.state-of-mind.de Franziskanerstraße 15 Telefon +49 89 3090 4664 81669 München Telefax +49 89 3090 4666 Amtsgericht München Partnerschaftsregister PR 563 -- users@sogo.nu https://inverse.ca/sogo/lists
