[OpenSIPS-Devel] Hang due to "no more nonces can be generated"

[Richard Revels]

Dan,

We are fighting a pkg_memory allocation error on our platform as  
well.  Are you saying that doing a fifo command such as dlg_list every  
few seconds would cause memory allocation errors for script processing  
over time?  This is on openser 1.3 rather than opensips 1.4 but the  
core dumps I have the bug tracker on is keeping me from doing any  
upgrading at the moment.
