Hello,
I'm experiencing the same problem as Philip Walker and others, on two different computers (Pentium II and III), both Windows-updated and CygWin-fromscratch-setup-reinstalled yesterday (i.e. XP-Pro SP1 and Cygwin 1.5.9-1, Cygipc 2.03-2 and PostgreSQL 7.4.1-3; see below 'cygcheck truncated output').
Whenever I launch a task which seems to need more memory, the server process gets terminated by signal 11 (i.e. based on my experience : when creating many tables at ones within a transaction or vacuuming/analyzing a large database ; I haven't been able to go any further, for my project-database is unusable on Cygwin while behaving just fine on our Linux/RedHat-based production machines).
I tried :
kill ALL unnecessary process on my machine (antivirus, vpn server, etc.), keeping just the bare minimum - no difference
lower shared buffers from 1000 to 20 - no difference
lower/extend vacuum mem from 1024 to 16384 - no difference
extend wal_buffers - no difference
turn fsync on and off - no difference
launch postmaster with -d 5 debugging-level - no further information (DEBUG : PorcessUtility ; DEBUG: reaping dead process ; LOG : server process (PID xxxx) was terminated by signal 11)
launch ipc-daemon2 with -d debugging-level - no output
I was able to go further in my project by :
suppressing the transaction blocks - suceeded to create the entire database schema
vacuum NOT analyzing the database - suceeded to vacuum the database
But...
still not able to vacuum-analyze database
and I supect that as soon as I will launch any other memory-greedy operation, result will be the same
I also tested :
create a different schema (i.e. stripping the unrequired parts until the .sql script which crashed my original schema : the tables creation script, originally transaction-wrapped) - no difference
Other symptoms/side-effects:
when crashing because of the "too"-large transaction blocks, the database would get corrupted and would prevent server to reinitialize until a new 'initdb' is done (LOG: Exception: STATUS_ACCESS_VIOLATION) ; reinitialize ok if crash occurs because of vacuum
I will try a 'strace' but I doubt my ability to interpret the results... and much more fix the problem. ;-)
WHAT ELSE CAN I DO ?
Please help,
Cedric
