After booting once computer found that BOINC crashed and restarted and HADAM model time has ben reset to some hours (see log below). After that HADAM model each time restarts and sends trickle message twice after starting BOINC client.

Additionally consumed time was reset to something near zero. I guess this time corruption is BOINC not project as I have seen similar time corruption also with 2 Einstein@Home workunits more than once.

Is it worth to continue the model?

System information: Linux, Fedora 8 x86_64, etc.

Did you Exit from BOINC before re-booting?
Highly recommended if you don\'t want to crash climate models.

Several trickles after a re-start is OK. If you look at the trickle file, you\'ll see that they are type \'cse\', whereas \'normal\' trickles are type \'orig\'.
type \'cse\' just tells the server that the model is back up and running.

As for continuing, is the day/month/year constantly advancing in the graphics?
If so, continue.
If it keeps jumping backwards, it may be best to abort.

Linux shut-down scripts stops BOINC automatically. I\'m using Fedora-8 boinc-client RPM which runs BOINC in daemon mode.

Text output from BOINC client shows that there are no backjumps (except of
using last checkpoint after restarting). In daemon mode graphics does not seenm to be working.

Tried to:
1) suspended CPDN model
2) restarted BOINC (/etc/init.d/boinc-client stop with following starting it)
3) resumed CPDN model

It still exited and restarted from checkpoint in the same way as in earlier included log.
