659.0. "Yet an other ACCVIO PCM crash" by BACHUS::WILLEMS (Johan Willems @BRO DTN 856-8739) Thu Mar 23 1995 14:22

A customer reported following problem with PCM


-------------------------------------------------------------------------------
Polycenter Console Manager dumps during "CONSOLE CONNECT ..."                   

PCM was (!!!) working properly for two days now (no more processes in RWMBX),
so we started to regain a bit of confidence in PCM at last.

BUT: this morning PCM betrayed us again ....

    Johan,
    
      That virtual address looks like ascii text so I speculate that when 
    we lost the connection a structure got deallocated and was then
    reused somewhere else. That PC is within a run-time library so we're
    not going to get very far with what we have. 
    
    Regs,
      Dan
