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
