I am getting the following errors:

2004-08-03 16:38:47 [SETI@home] ACTIVE_TASK_SET::insert(): can't delete file slots\\\stderr.txt
2004-08-03 16:38:47 [SETI@home] Unrecoverable error for result 02ja04ab.18465.10722.467332.176_2 (Couldn't start the app for this result: error -110)

for every work unit that was on queue and hadn't been processed yet. After these errors all unprocessed units were deleted leaving only the completed units waiting for upload.

I have checked stderr.txt in the specified directory, there is nothing wrong with this file and BOINC/SETI should be able to delete it.

I am running BoincLogX 1.05, but as far as I can tell this program only accesses state.sah and not stderr.txt.

I can't get any new work units at the moment, so I can't check whether the problem was temporary or recurring.
