apache hangs after some hours of running





------- Additional Comments From [EMAIL PROTECTED]  2002-07-24 02:27 -------
I'll mention this, in case it is significant...

We have a program that remotely monitors to see if our servers are up. The 
program also 
monitors apache.  It senses the apache hanging, but no matter what I do to the 
code, 
setting a SIGNAL and an ALARM in all of my socket code (open, read/write and 
close all 
have alarms around them) it MOSTLY will not catch it.  In other words, the call 
to read 
from the socket reads and an ALARM does not break it out of the read.

Additionally, in support of this, I also noted that a HUP to the parent process 
(apache) 
does not free it up.  Additionally, if I TELNET to port 80 of the hung process 
IP address, I 
get a connection from apache, but issuing a "GET /" causes a hang (as I 
previously 
reported)... HOWEVER, trying to break that hang with a CONTROL-C or other 
signal, 
OTHER than a kill, also refuses to free the hang.

So, it seems to me that other than a kill signal, when these are hanging other 
signals are 
also refused (e.g., alarm, control-c (int)).
