Re : Re: Found Memory Leak in Squid at cbdata

Hello Henrik,
This is the frequest memory leak I am sending u log file telling memory leak info generated via XMALLOC_xxx options in squid.
This is log file after squid has served only 2 requests.

Actually i am facing vary serious problem of memory leak in squid.

Squid is serving about 1200 request/minute on redhat linux box with kernel 2.4 and memory 1GB RAM
Memory utilized by Squid is going to increase with time.
So we need to restart squid once daily.
Can u give me direction to handle this problem of squid.
Waiting for reply

Yes, there is many such one-time memory leaks in Squid where Squid
allocates some memory on startup but never frees it on shutdown.
There is little to be gained from spending lots of time on getting
rid of this type of memory leaks as the memory is automatically freed
when the application (squid) terminates even if not explicitly freed.

The memory leaks which matters most for Squid is the leaks related to
normal processing, i.e. the kind of leaks which can leak more than
once during the lifetime of Squid.

Henrik
