<key>CSCuq31464</key> - IOS-XE 3.13S &quot;fman_fp_image&quot; Kernel Memory Leak Due to &quot;fw-zone-pair&quot;
Hello   about this bug there are some obscurities. The release 15.5(1)S is under &quot;known affected Releases &quot; and &quot;Known Fixed Releases&quot;. Which one is right? For Release 3.14.0 S we could not find anything about bug in release note. Is there now any IOS-XE Version in which the bud is fixed?   Thank you for your Feedback in advance.   Regards
