Old Python binary eats all mem after upgrade to 2.28

[Michael Brunnbauer <brunni at netestate dot de>]

hi all,

I just upgraded to glibc 2.28 and everything seems to run fine - except this
old binary of Python 2.1.3 from 2002 that came precompiled with Zope 2.6.0.
When I start it on the command line, it starts eating up all memory until
it gets killed by the oom-killer. strace looks like this:

mremap(0xe64aa000, 225259520, 225263616, MREMAP_MAYMOVE) = 0xe64aa000
mremap(0xe64aa000, 225263616, 225267712, MREMAP_MAYMOVE) = 0xe64aa000
mremap(0xe64aa000, 225267712, 225271808, MREMAP_MAYMOVE) = 0xe64aa000
mremap(0xe64aa000, 225271808, 225275904, MREMAP_MAYMOVE) = 0xe64aa000
mremap(0xe64aa000, 225275904, 225280000, MREMAP_MAYMOVE) = 0xe64aa000
mremap(0xe64aa000, 225280000, 225284096, MREMAP_MAYMOVE) = 0xe64aa000
...

I am in the very difficult process of moving away from that particular legacy 
but this will take time. Also I'm concerned about other old binaries that may 
stop working.

Any idea what is going on?

Regards,

Michael Brunnbauer
