Symptom
You are running the Maintenance Optimizer but the execution keeps stopping with the error,
500 Connection timed out
Solution
Look for icm/server_port_X parameter of PROT=HTTP. Increase or add the PROCTIMEOUT onto it. Example,
icm/server_port_0 = PROT=HTTP,PORT=1080,TIMEOUT=30,PROCTIMEOUT=1000
