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 ,
