[rt-devel] HTML::Mason 1.15 with RT 2.0.15 spins CPU

[Blair Zajac]

Just a heads up, it looks using HTML::Mason 1.15 has a side
effect that Apache uses all available CPU cycles when I point
my browser at my local RT 2.0.15. installation's home page.
The RT page never loads.

To make certain it's Mason 1.15, I installed HTML::Mason 1.14
into the same Perl installation, stopped and started Apache and
RT loaded just fine.  Installing 1.15 again, restarting Apache
caused the same spin problem.

This is on RedHat 8.0 with Apache 1.3.27 and mod_perl 1.27.

# top
  PID USER     PRI  NI  SIZE  RSS SHARE STAT %CPU %MEM   TIME COMMAND
 6429 root      15   0 15124  14M 15008 S    96.4  5.9   1:12 httpd1

Attaching strace to the process didn't show a whole lot:

# strace -p 6429
select(0, NULL, NULL, NULL, {0, 775341}) = 0 (Timeout)
time(NULL)                              = 1034637776
wait4(-1, 0xbfffade4, WNOHANG, NULL)    = 0
select(0, NULL, NULL, NULL, {1, 0})     = 0 (Timeout)
time(NULL)                              = 1034637777
wait4(-1, 0xbfffade4, WNOHANG, NULL)    = 0
select(0, NULL, NULL, NULL, {1, 0})     = 0 (Timeout)
time(NULL)                              = 1034637778

Best,
Blair
