Hi there folx,
I've compiled those ones with "-g" and have connected to them
via gdb. It's really weird - they all are in crypt() fcall,doing
something crazy - since they all are in the list of the processes
consuming the most amount of time !
So as the time flow - more and more erpcd's get stuck in crypt(),
which leads to huge load averages finally.
The idea of the sequential search thru the acp_passwd doesnt
contribute much to it - it's suprisingly fast.
So what the heck is going on ... ? I use DES crypt() on this
computer. The parameters to the crypt() look pretty innocent to me :(
Here goes the small transcrypt from the gdb session:
( it was invoked as : gdb erpcd PID)
Reading symbols from /usr/libexec/ld.so...done.
