Subject:	asyn/stream hang on (very long email, sorry in advance)

Dear All,
I'm working to make an IOC which has to read strings on rs232; 
these strings are continuously sent from a box.
Up to now I'm working just only to
read the this string:

"KS,[counter],[encoder0],[encoder1],[encoder2],[encoder3]"

The IOC works very well to few hours,
after that it's (the communication) hangs-on (??) 

Follow the protocol:
----------
InTerminator = LF;
#
ExtraInput = Ignore;
ReplyTimeout = 1000;
ReadTimeout = 1000;
LockTimeout = 5000;

knob_id { in "KS,%d,%*d,%*d,%*d,%*d" ; }
knob_0 { in "KS,%*d,%d,%*d,%*d,%*d" ; }
knob_1 { in "KS,%*d,%*d,%d,%*d,%*d" ; }
knob_2 { in "KS,%*d,%*d,%*d,%d,%*d" ; }
knob_3 { in "KS,%*d,%*d,%*d,%*d,%d" ; }

---------- 
Follow the template db:
----------
record(ai, "$(device):KNOB_ID")
{
field(DESC, "$(device):KNOB_ID VALUE")
field(DTYP, "stream")
field(INP, "@psiKnobbox-$(rs).proto knob_id $(port) 0")
field(SCAN, "I/O Intr")
}

record(ai, "$(device):KNOB_0")
{
field(DESC, "$(device):KNOB_0 VALUE")
field(DTYP, "stream")
field(INP, "@psiKnobbox-$(rs).proto knob_0 $(port) 0")
field(SCAN, "I/O Intr")
}

record(ai, "$(device):KNOB_1")
{
field(DESC, "$(device):KNOB_0 VALUE")
field(DTYP, "stream")
field(INP, "@psiKnobbox-$(rs).proto knob_1 $(port) 0")
field(SCAN, "I/O Intr")
}

record(ai, "$(device):KNOB_2")
{
field(DESC, "$(device):KNOB_2 VALUE")
field(DTYP, "stream")
field(INP, "@psiKnobbox-$(rs).proto knob_2 $(port) 0")
field(SCAN, "I/O Intr")
}

record(ai, "$(device):KNOB_3")
{
field(DESC, "$(device):KNOB_0 VALUE")
field(DTYP, "stream")
field(INP, "@psiKnobbox-$(rs).proto knob_3 $(port) 0")
field(SCAN, "I/O Intr")
}

---------- 

The asynDebug on IOC shell give me:
