VCS may crash and report a SIGSEGV fault:
Symptoms: Cisco VCS may crash, and an alarm be raised stating that an unexpected
software error was detected in app with a SIGSEGV fault. A crash report will also be
generated and when this is analyzed a call to sha1_block_data_order() in libcrypto is seen in
the trace back.
Conditions: This was on a Cisco VCS release X7.0.1
Workaround: There is no workaround at this time.

No presence PUBLISH generated by PUA in SIP->H323 interworked call in VCS cluster:
Symptoms: sometimes in-call presence is not published by PUA for H.323 calls.
Conditions: H.323 endpoint must register to a cluster peer and the call must come in
through another peer in the cluster. (If the call arrives on the same peer to which the endpoint
is registered, the in-call presence will be fine.)
Workaround: dual register endpoints as SIP and H.323.
Symptoms: sometimes in-call presence is not published by PUA for H.323 calls.
Conditions: H.323 endpoint must register to a cluster peer and the call must come in
through another peer in the cluster. (If the call arrives on the same peer to which the endpoint
is registered, the in-call presence will be fine.)
Workaround: dual register endpoints as SIP and H.323.

The VCS fails to listen on call signaling ports:
Symptoms: The VCS fails to listen on call signaling ports after a reboot / restart / upgrade.
Conditions: The issue is due to a race condition as ports are assigned during bootup. It
occurs rarely.
Workaround: It could potentially be cleared by a restart.

The CPU load of the VCS increases dramatically in X7 when %localdomains% is used
in pattern matching.
Symptoms: The VCS has a high CPU load, reducing responsiveness.
Conditions: The issue is due to the increase in the number of local domains permitted in X7,
and the way in which the %localdomains% keyword is expanded in pattern matching.
Workaround: Explicitly list domains rather than use %localdomains%.
