Hello,
a customer of ours has an old PC (CoreDuo, 4 GB RAM, Windows XP)
that's running PostgreSQL. Yesterday PostgreSQL started crashing
suddenly with the following log

2016-03-23 10:43:30 CET PANIC: could not write to log file 6, segment
217 at offset 3366912, length 8192: Invalid argument
The machine has 4,5 GB of allocated memory (thus swapping).
I googled to get some references to what's above and that's results:
Winsock 10004 means Interrupted function call;
Error code 1450 should mean "Insufficient system resources exist to
complete the requested service"
Winsock 10055 means "No buffer space available"
Winsock 10061 means "Connection refused"
The only thing I couldn't get some serious reference was the PANIC
message that's in the last row.
But putting the other things together, I figured out the machine is too
obsolete and ran out of system resources, causing error 1450, which
Winsock 10055 is solely a consequence, and probably the PANIC is
generated by this mess.
Am I right?
Thanks in advance,
Moreno.
