Hi,
I found the following in the logs of a server that crashed:
Mar 19 14:09:28 sc4 kernel: Assertion failure in ext3_free_blocks() at
balloc.c line 358: "bh->b_committed_data != NULL"

Searching through the ext3 mailing list I found the following post which
had a similar experience:
http://www.redhat.com/mailing-lists/ext3-users/msg02666.html
However, there was no reply to his query.
The server in question runs squid which handles high volume of traffic
every day.
Debian 2.2 (potato)
kernel 2.2.19
ext3-0.0.7
1024 MB RAM
Pentium III 850 Mhz
squid 2.4.STABLE4
Any help is much appreciated. Btw, would changing the kernel to 2.4.x
help in this situation?
Rgds,
Meng Kuan
