14	C_Initalize should be called after each fork	alon.barlev@…	somebody	"Hello,

The pkcs11_eventmgr first C_Initialize then becomes a daemon... The PKCS#11 standard states that after fork the user must call C_Initialize again, in order to allow proper library initialization at new process.

Also, don't quit on major errors... try to reinitialize.

I've sent this a long time ago...

Please consider the following patch:
