* Too many private FDs

Hi folks,

is anyone able to explain the following error-message extracted from
the "server.log"?

-- ERROR:  AllocateFile: too many private FDs demanded
-- pq_recvbuf: unexpected EOF on client connection
-- IpcMemoryCreate: shmget failed (Identifier removed) key=5432007,
   size=96424, permission=600
-- SISegmentGet: failed: Identifier removed
-- FATAL 1:  CreateSharedInvalidationState: failed segment init
-- FATAL 1:  AttachSLockMemory: could not attach segment

The main postmaster-process dies, still leaving the other postgres-
processes active (but not working). This happens roundabout once a
day caused by different workstations and different functions.

A few environment information:
PostgreSQL 6.5.2 w/ SuSE 6.0 (2.0.36) running on a SNI-Primergy 070
Access-method: w/ Insight's ODBC-driver (6.5/0006) from MS-Access

Thanx in advance
- Rolf

I have had similair problems with the Informix Online database engine. 
 You need to be running a 2.2.x kernel and to use the sysctrl 
interface to increase the number of file handles (by default limited 
to 1024) and possibly the maximum shared memory size.

Do you use password verification for any of your clients?

There is a file descriptor leak in the 6.5.* postmaster that is
triggered when an invalid user name is presented to the password
check routine.  Add a FreeFile() call to the bottom of the check
routine, like this:

inline patch 1: src/backend/libpq/password.c (+2/-0 lines) download inline-1.patch*** src/backend/libpq/password.c.orig Tue May 25 12:09:00 1999 --- src/backend/libpq/password.c Wed Dec 1 10:30:46 1999 *************** *** 90,95 **** --- 90,97 ---- return STATUS_ERROR; } } + + FreeFile(pw_file); snprintf(PQerrormsg, ERROR_MSG_LENGTH, "verify_password: user '%s' not found in password file.\n",
This is fixed in current sources and will be fixed in 6.5.4, if there is another 6.5.* release... If you *don't* use this style of authentication then we need to look harder :-( regards, tom lane ^ permalink raw reply [nested|flat] 3+ messages in thread
