Description

Hi,

The server appears to crash when it runs out of FDs. Changing max-fds from 1 k to 2 k avoids the crashes. Strace showed memory corruption.


fdevent.c.171: aborted
*** glibc detected *** malloc(): memory corruption: 0x0a319dd8 ***
*** glibc detected *** free(): invalid next size (fast): 0x094023b8 ***

Linux: 2.6.9-42.0.2.ELsmp

Just FYI: the three lines are from three different crashes.
