dear colleagues, when processing with mosflm626 in batch mode (but not when processing interactively) we very frequently get mosflm crashes with 'system 5 i/o' errors. the problem is somewhat elusive, since the crashes are not strictly reproducible. when i process the same dataset using the same parameters 10 times, it may crash in seven attempts and run fine in three. the problem also is not reproducible on all hardware. mosflm gives no further details as to the i/o unit that causes the problem. the crashes exclusively occur in problematic datasets and can almost always be overcome by subtle changes in the processing parameters. while i can automate the process of parameter adjustment, this behaviour consumes more computing resources than desirable, and i was wondering whether anybody would have observed this and would have an idea (short of buying new hardware or installing a different operating system) about how to catch these crashes cleanly. we are using mandrake 10.2 with linux 2.6.11-12mdksmp and i have ccp4-6.0.1 installed. the problem occurs with mosflm from this distribution, but also with previous as well as the very latest release from harry powell`s pages. any ideas welcome ... greetings ingo -- Ingo P.
