Supervising multiple gen_servers with same module / different arguments
- by Justin
Hi,
I have a OTP application comprising a single supervisor supervising a small number of gen_servers. A typical child specification is as follows:
{my_server,
{my_server, start_link, [123]},
permanent,
5000,
worker,
[my_server]}
No problems so far.
I now want to an add extra gen_server to the supervisor structure, using the same module Module/Fn as above, but different arguments, eg
{my_server_2,
{my_server, start_link, [123]},
permanent,
5000,
worker,
[my_server_2]}
I thought this would work, but no:
=SUPERVISOR REPORT==== 15-Apr-2010::16:50:13 ===
Supervisor: {local,my_sup}
Context: start_error
Reason: {already_started,<0.179.0>}
Offender: [{pid,undefined},
{name,my_server_2},
{mfa,{my_server,start_link,[]}},
{restart_type,permanent},
{shutdown,5000},
{child_type,worker}]
Do the module arguments in the second element of each child specification need to be different ?
Thanks,
Justin
