Linux memory problem with TIS firewall
We have installed a TIS firewall on a Red Hat Linux (Kernel version 2.0.34) computer.
Since we installed it, the computer crashes once or twice a day with this error:
- Unable to handle kernel paging request at virtual address "xxx" for example e03b653c and displays a list of addresses and stack contents as well as :
- Process http-gw (pid: ....)
and at the end the message:
- kfree of non-kmalloced memory ....
The computer is a Pentium MMX 166 with 32 Mb of memory. The hard disk contains a swap partition of 400 Mb in a 2.8 Gb. The only application running is the TIS firewall. We downloaded the most recent version from your ftp site last week.

Could you please send us the ksymoops output of such an event? That would give us some more detail to work with...

How much of that swap is actually used? If there's a memory leak somewhere (the firewall package eg.) and it fills up the memory in a certain time things might go wrong.
OTOH, I have heard some rumours of more memory leaks being fixed in kernel 2.0.36.

??? Most recent version of what? Kernel 2.0.34 is certainly not the most recent one... The TIS firewall is not something we know of...
Linux is not a company, so there's not really a 'we' and certainly no 'our ftp site' :)
