[Zope-dev] Zope gets stuck

[Itamar Shtull-Trauring]

stuck means infinite loop - won't respond to HTTP requests, although the
monitor still works. I'm running http_load, with attempted 50 requests a
second for 10 seconds on a computing intensive method (convert long article
from structured text, do replace, split, replace, put back together - DTML
and pythonmethods.)  With 10 requests a second Zope does fine. 50 requests a
sec against a simple method also works fine.

While running http_load Zope does:
