[Mauiusers] maui crashes constantly

[Marcin]

Hi,

I have a cluster (~120 machines) with torque 2.1.0p0 and maui running 
very stable for over a year. Last week major power failure happened, so 
I decided it's very good moment (everything was down) to update os 
Gentoo Linux). Configuration was also extensively changed, including 
maui's one. After that maui crashes constantly with such messages:

*** glibc detected *** malloc(): memory corruption: 0x000000000273b180 ***
*** glibc detected *** free(): invalid next size (normal): 
0x000000000273b160 ***

and so on. Sometimes it runs for several hours, sometimes for 2-3 
scheduling cycles only. My first guess was that glibc is buggy, so I 
verified that it crashes the same way for glibc 2.3.5-r3 (the one which 
was installled before upgrade - now it crashes), 2.3.6-r3 and 2.3.6-r4 
(the latest one available in gentoo). Also two versions of maui were 
checked - 3.2.6p16 and maui snapshot dated 23-May-2006 16:20. I am 
unable to get rid of this problem. It is maui specific for sure - maui 
is the only one to crash that way, everything else works fine all the 
time as it was.

If anyone decides it is important to get rid of this "undocumented 
feature", all diagnostics data can be sent by me (config files, files 
created by maui, core cumps etc.).
