DOCUMENT:Q263064 08-MAY-2002 [exchange] TITLE :XADM: Blackberry Service Stops If Exchange Server Comp. Offline PRODUCT :Microsoft Exchange PROD/VER::5.5 OPER/SYS: KEYWORDS:exc55 ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Exchange Server, version 5.5 ------------------------------------------------------------------------------- SYMPTOMS ======== The Blackberry pager service can monitor multiple Exchange Server computers for new e-mail activity. If one of the monitored Exchange Server computers goes offline, the Blackberry pager service may stop responding, or "hang." CAUSE ===== This problem can occur because one thread is waiting for a server response to a remote procedure call (RPC). However, a response never comes because the Exchange Server computer is offline. In some instances, two other threads are blocked because they are waiting for the first thread to finish, and many other threads are blocked because they are waiting for a critical section that is held by one of the two threads. RESOLUTION ========== A supported fix is now available from Microsoft, but it is only intended to correct the problem described in this article and should be applied only to systems experiencing this specific problem. This fix may receive additional testing at a later time, to further ensure product quality. Therefore, if you are not severely affected by this problem, Microsoft recommends that you wait for the next Microsoft Exchange Server version 5.5 service pack that contains this fix. To resolve this problem immediately, contact Microsoft Product Support Services to obtain the fix.
