Also (obvsly) we aren't able to get a new connection after hitting max fd limit.. Thx, Prasanna. -----Original Message----- From: Mavinakuli, Prasanna (STSD) Sent: Wednesday, August 09, 2006 10:10 AM To: pgsql-general@postgresql.org Cc: Mavinakuli, Prasanna (STSD) Subject: Too many open files from postgres. Hello All, We are using postgres with HP-UX. Usually We will have many records,and will do vacuum once in 2 days. We have observed that postgres opens many files in data directory And won't close till next vacuum (I experience it) When it hits max limit, we won't able to open any other files. So what's the solution ..? 1)Is it really postgres issue..doesn't it close opened files immediately after completion of writing..? If so how do we handle the scenario of hitting max fd within next immediate vaccuming..? 2)ideally what's the size of each file..?when it opens second file..?what's criterion..? I can observe files of different sizes in the same directories..? Thx in advance, Prasanna. *lsof* gives following output. postmaste 22481 sfmdb 9u REG 64,0x8 16384 6562 /var/opt/sfmdb/pgsql/base/17142/16635 postmaste 22481 sfmdb 10u REG 64,0x8 8192 4373
