Table 1. Fixed issues
Issue number & SR number	Problem summary
SCI-65334 SR# 134810840	During non-disruptive upgrade to PowerFlex 3.6, the SDS maintenance mode takes longer when the MDM returns an incomplete query to the PowerFlex Gateway.
SCI-68154	The SDC container used supervisord to run and log the diagnostic message. All the kernels do not support the diagnostic message switch which caused the supervisord to return the diagnostic messages in an infinite loop and consume excessive CPU.
SCI-67542 SR# v1007162	Disruptive upgrade occurred on SDC during RCM upgrade. Deadlock on locking Octet in L2P directory between the L2P Page merges flow. The L2P split-upgrade flow that is invoked causes a disruptive upgrade due to SDS IO timing out.
SCI-68153	The SDC-SDS TCP disconnected when the SDS host was hard reset while establishing the security communication link. The keepalive manager does not close the socket due to inactivity and remained open indefinitely.
SCI-65052 SR# 133347603	The SDS disconnected when a large set of data was allowed into the Protected Maintenance Mode. The MDM delayed the RoleSwitch and created a timeframe which resulted in an IO error until the SDS responded to all the combs.
SCI-66526 SR# 139180450	During an IO background operation, you must split few operations to multiple MD pages to fit in the correct size of an FG device. A new write with an existing background operation leads to an overflow in the MD buffer space and causes the SDS crash when detected.
SCI-66575	IM scripting “stop process on script failure" does not stop on failure and the indicator may be overridden. If validateNoCriticalFailureCommand indicates a failure due to a flag in criticalCommandFailedArr, the sequence stops at exit-SDS-from-MM since this command always runs.
SCI-65531 (SR# 135236911)	When you unmap a volume from the latest SDC version, the volumes remain mapped even if the unmap operation is completed.
SCI-67424 SR# v1005052	SDS decoupled due to panic "ALWAYS_ASSERT IO takes too long". Incorrect locking order of L2P Directory octet and octet counters leads to a deadlock between L2P Page merge flow and QueryCapacityUtilization. This blocks many IO operations indefinitely until SDS panics due to timeout.
SCI-67007	Execution of sas3ircu triggers SVM crash on PowerEdge 15G-based hosts. For details, see DTA 199549.
SCI-66906	Tomcat versions 8.5.79 and earlier is exposed to CVE-2022-29885. PowerFlex Gateway does not use the clustering feature and is not exposed to the issue.
SCI-65370	The exclude log collection check box for the SDC log collection was removed. The check box is restored to exclude and include the node log collection.
SCI-62416 SR# 119473468	When running scripts on host feature, the operation logs does not check the script files in nodes.
