Symptoms

MCP cores when importing a configuration with 12000 nested address lists and auto-sync enabled. /var/log/ltm contains messages similar to the following: -- err clusterd[7274]: 013a0004:3: IO error on recv from mcpd - connection lost -- info sod[7953]: 010c0009:6: Lost connection to mcpd - reestablishing. -- notice chmand[7594]: 012a0005:5: resetting chmand services -- err snmpd[7952]: 010e0001:3: Cannot communicate with MCPD server. -- err mysqlhad[7596]: 014e0006:3: MCP Failure: 1. -- err zxfrd[7962]: 0153e0f7:3: Lost connection to mcpd. -- err tmrouted[6299]: 01910013:3: FATAL error: 6 irrecoverable MCP I/O error (Unknown error 16908291). -- err alertd[7280]: 01100042:3: Failed with MCPD at: MCP msg receive (16908291). -- err alertd[7280]: 01100042:3: Failed with MCPD at: Socket read (16908291).

Impact

mcpd cores.

Conditions

-- AFM configuration. -- Devices in a device group trust configuration. -- Device group configured with Autosync enabled. -- Importing a configuration with a very large number of nested address lists (for example, 12000 nested address lists).

Workaround

Split the configuration into smaller chunks (e.g., 1000 address lists each) and load them one at a time.

Fix Information

None
