hello,

i'm running apache 1.3.19 on freebsd 4.3-RC cvsupped 03/23/01.  apache
was built by hand with php4.0.4pl1 and apache_1.3.19+ssl_1.42.  in the
parent server error log, i am getting thousands of the following
message:

httpsd in free(): warning: chunk is already free.
httpsd in free(): warning: chunk is already free.

occasionally it will say "page is already free." instead of chunk.

am i correct in assuming that this means httpsd uses freebsd's libc
and that the free() function from libc is reporting this warning
message?

how should i go about trying to fix it?  it fills up my logfile
partition - yesterday i had a 730MB error_log.

i had this same problem on freebsd 3.4-release as well.

here is some info:

a search turned up this page:
http://www.freebsd.org/cgi/query-pr.cgi?pr=gnu%2F7821

which refers to a similar problem with free().  i have no idea if it's
related/helpful though.
