[Zope] Heap Corruption Problem

[Dieter Maurer]

Apparently, we have a serious heap corruption problem.

The problem manifests itself in different ways:

  The Python process
    * receives signal 9 (SIGKILL) by Solaris 2.7
    * receives signal 11 (SIGSEGV)
    * enters an infinite loop (and blocks the complete process)

In all cases, the analysis detected that the fatal event
occured in a memory management function, not always the same,
however.

The problem occurs about 1 to 2 times per day on a lightly
loaded site (still under construction and test).


Environment:

  Zope 2.1.6 binary release for Sparc-Solaris 2.6
  Solaris 2.7
  ZOracleDA 2.1.0 with Oracle 8.1.6
  no other C level extensions



I will keep you informed.
