• vmware-vmrc-2.5.0-122581.i386.tgz: vmware-vmrc-2.5.0-122581.i386.tgz

The problem is not solved in 1.0.6. As the attachment obove points out - the problem was not in 1.0.0 like foswiki.org (why not the actual release? Also not in the trunc-foswiki. What cat I do - it doesnt work with or without modperl. I have tested with the file sise and saw:

-rw-r--r-- 1 fischer urz 11113368 23. Jun 08:25 T2 -rw-r--r-- 1 fischer urz 12226599 23. Jun 08:27 T3

T2 could be attached - T3 goes to the described error -> blank page and the 2 lines in the error.log The problem becomes painful for me so I put the prority to Urgent ...

The problem is probably due to your running out of disc space (possibly in /tmp), or the apache process timing out. I doubt it's anything to do with Foswiki per se, more likely to be your web server configuration.

FYI I don't have any problem uploading a file that size.

Günther, could you run grep -r 'viewerror' to see where the reference to .../bin/viewerror comes from in the first place? Are you using any 'non-default' Foswiki plugins and/or web server modules which possibly affect the upload process (virus scanners, intrusion detection engines, etc)?

I think I found an error on my side, so I take priority to low. I will report later. Thanks to Crawford and Markus.

-- GuentherFischer - 23 Jun 2009

Oh terrible - I changed from RcsLite to RcsWrap and no further problems with attach files and delete attachments. So I think there is a serios problem with RcsLite and attach - I change the priority back to normal. Can anybody try modperl, RcsLite and attach big files to reproduce the problem. I can stay with the situation but I think its a real problem.

I really don't think anyone is going to spend time on this. Binning it.
