[maker-devel] "ALRM" isn't numeric in exit - MAKER warning message

[Carson Holt]

Hi Marivi,

The only time MAKER uses the ALRM signal is during exit. Sometimes MPI_Finalize can freeze (it has to do with the fact it is being called from Perl). So we set an alarm just in case. Then if it takes to long we assume it is frozen and let things exit in a less than graceful way rather than let it block forever (it is already finished after all). The complaint you get may be because your system doesn’t support the alarm signal or forks.pm (which tries to intercept signals) is having an issue. Or it may just be ugliness related to parts of the process being killed with other parts still being active (it is an ungraceful exit after all). Or it may be another source of the ALRM all together (but I assume it is the MAKER ALRM given that it happens right after MAKER says it is finished). 

Thanks,
Carson
