Opened: Sep 27, 2018

Severity: 3-Major

Symptoms

Configuration loading crashes while loading hundreds or thousands of bot-defense profiles at once. The system logs messages in /var/log/ltm: -- err mcpd[8967]: 01070712:3: Caught configuration exception (0), MCP call 'mcpmsg_set_ulong_item(msg, CID2TAG(cid), val)' failed with error: 16908292, 01020036:3: The requested user role partition (admin Common) was not found. -- err mcpd[8967]: 01070001:3: Failed to allocate memory for size 66256896 at framework/MCPProcessor.cpp:1041. -- crit tmsh[640]: 01420001:2: The connection to mcpd has been lost, try again. : framework/RemoteMcpConn.cpp, line 74.

Impact

MCP might crash or be blocked for a long time. The system cannot perform traffic management operations, report system status, or allow reconfiguration, and other daemons are also affected.

Conditions

Loading configuration with hundreds or thousands of bot-defense profiles.

Workaround

Create bot-defense profiles one at a time rather than loading a configuration with hundreds or thousands of bot-defense profiles at once.

Fix Information

The configuration load no longer crashes while loading hundreds or thousands of bot-defense profiles at once.
