sm_perl - how to catch USR1/USR2 signal?

I got a question regarding signals: I am running a perl script as a demon, that shall re-read it's configuration when receiving a USR1 or USR2 signal. Script works fine when run with the stock (machine based) perl, but will not work propperly when running with sm_perl. Sending SIGUSR2 triggers a stack dump, SIGUSR1 seems to be ignored. "Trussing" the process however shows, that the USR1 signal is delivered, but caught somewhere in another layer, maybe sm_perl itself.

 

Any ideas, how to proceed and make this work?

 

Thanks in advance,

Gunter
