PR_Accept() failed, error -5971 (Process open FD table is full
(libdb: PANIC: fatal region error detected; run recovery)
We have a misbehaving system or application which is opening connections to our DSEE instances but never BINDing or closing its connections. When this behavior occurs we see in the log the error "PR_Accept() failed, error -5971 (Process open FD table is full)." This error is repeated many, many times (during the last instances it was repeated over 500,000 times in less than one hour). Eventually we see the database get corrupted (libdb: PANIC: fatal region error detected; run recovery).
Customer had a bad application that was only opening new connections without a proper BIND/UNBIND/close. This used up the Directory Servers "file descriptors" before they could be closed/freed.
