Rogerio,
I think postgre allows less connection than your max_connections setting. From: dbmail-boun...@dbmail.org [mailto:dbmail-boun...@dbmail.org] On Behalf Of Rogerio Pereira Sent: sexta-feira, 31 de Outubro de 2014 14:29 To: dbmail@dbmail.org Subject: [Dbmail] max_db_connections Hi, I need suggestions about max_db_connections. Imapd usually hangs in my DBmail instance running 3.1.17 in a daily basis. dbmail-imapd[10702]: [0x18e6f90] Alert:[db] db_con_get(+254): Thread is having trouble obtaining a database connection. Try [0] pool[10726]: segfault at 0 ip:00007fc0c2b53e20 sp 00007fc0b9fa5660 error 4 in libzdb.so.9.0.2[7fc0c2b4b000+1a I decided to change max_db_connections from 10 to 20. Is it OK? What are the chances to get it worst than before? My server has 1900 users, average of 30 simultaneous user connections, PgSQL 9.3 in a separate server and 120 GB total DB size. Another question: Pop3d does not throw this error in dbmail.err. I guess this service will be impacted by the same DB imapd connection issue. Is this pop3d error a symptom of the same problem? dbmail-pop3d[17231] general protection ip:7ffd411f180a sp:7fff0c6799c8 error:0 in libdbmail.so.0.0.0[7ffd411ad000+6b000] Regards. Rogerio
