It happened to me twice today that clicking one of the recently-modified-items in my weblog produced a strange outcome. I still get "my" url in the address-field, but a completely different page (see screenshot at left). When I reloaded the page, everything was alright again.

The other time this happened - was it a page from the same weblog or a different one?

I've checked the log files and there's some evidence that the bug happens /after/ Helma processed the request. Helma log file says:

antville/zack/RPC2 0 marked, 0 inserted, 0 updated, 0 deleted ... antville/mehrwortsteuer/stories/205043 0 marked, 0 inserted, 0 updated, 0 deleted ...

so Helma correctly processes both requests. (Also the processing times suggest that the mehrwortsteuer page has actually been generated). However, in the Apache log file we have

"POST /RPC2 HTTP/1.0" 404 20071 ... "GET /stories/205043/ HTTP/1.1" 404 20071

Thus both requests suddenly have the same response code and the same response length. I am pretty sure that this does not happen in Helma after the requests were handled separately and correctly. The main suspect for me is mod_jk, which also generates huge error logs on antville. I'm all for updating mod_jk as soon as possible and see if the error log ends.
