Hi ,
We are using Postgres 8.4 and its been found going into recovery mode couple of times. The server process seems to fork another child process which is another postgres server running under same data directory and after some time it goes away while the old server is still running. There were few load issues on the server but the load didnt went above "32".
We are running opensuse 10.2 x86_64 with 32Gb of physical memory.
Checking the logs I found that theres a segmentation fault ,
Sep 26 05:39:54 pace kernel: postgres[28694]: segfault at 0000000000000030 rip 000000000066ba8c rsp 00007fffd364da30 error 4
gdb dump shows this

Any suggestions what is causing this segmentation fault?
