This PBX has about 100 registered SIP clients, along with 23 PRI channels,
2 inbound/outbound SIP trunks and around 100 IAXModems registered to it. It
primarily handles faxing.
I am not using any non-standard channel drivers. I am using the T.38
gateway funcionality.

The jist of the dialplan is this: (example of the PRI and a SIP trunk,
inbound)

[pri-in]
exten => _X.,1,Set(__FROM_DID=${EXTEN})
exten => _X.,n,Set(FAX_IDX=700)
exten => _X.,n,Set(MAX_IDX=719)
exten => _X.,n,Goto(dial-hylafax,s,1)

[sip-trunk-in]
exten => _X.,1(normal),Set(__FROM_DID=${EXTEN})
exten => _X.,n,Set(FAX_IDX=950)
exten => _X.,n,Set(MAX_IDX=959)
exten => _X.,n,Set(FAXOPT(gateway)=yes)
exten => _X.,n,Goto(dial-hylafax,s,1)

[dial-hylafax]
exten => s,1,GotoIf($["${FROM_DID:0:1}" = "1"]?prune:cont)
exten => s,n(prune),Set(__FROM_DID=${FROM_DID:1})
exten => s,n(cont),GotoIf($[${FAX_IDX} <= ${MAX_IDX}]?tryfax:nofax)
exten => s,n(tryfax),Set(STATE=${DEVICE_STATE(Custom:iaxmodem${FAX_IDX})})
exten => s,n,NoOp(${STATE})
exten => s,n,Set(DEVICE_STATE(Custom:iaxmodem${FAX_IDX})=INUSE)
exten => s,n,Dial(IAX2/iaxmodem${FAX_IDX}/${FROM_DID},60,g)
exten => s,n,Goto(s-${DIALSTATUS},1)
exten => s,n(nofax),Playtones(busy)
exten => s,n,NoOp(NO MODEMS AVAILABLE)
exten => s,n,Wait(20)
exten => s,n,Hangup()
exten => s-ANSWER,1,NoOp(IAXMODEM HANGUP)
exten => s-ANSWER,n,Set(DEVICE_STATE(Custom:iaxmodem${FAX_IDX})=NOT_INUSE)
exten => s-ANSWER,n,Hangup()
exten => _s-.,1,Set(FAX_IDX=${MATH(1+${FAX_IDX},i)})
exten => _s-.,n,Goto(s,1)
exten => h,1,Set(DEVICE_STATE(Custom:iaxmodem${FAX_IDX})=NOT_INUSE)

The current state requires me to restart Asterisk almost every day.
I'm also seeing this on a completely different machine after upgrading from
Asterisk10 to 11.
