AS5350: Following errors and tracebacks observed.
%SIP-3-INTERNAL: DNS Task Queue is FULL -Traceback= 0x60460880 0x61423724 0x613C2C9C 0x613EA948 0x613FC8E8 0x6144F9C4 0x6144FC60

%SIP-3-QUEUE_ERROR: Unable to enqueue event SIPSPI_EV_DNS_RESOLVE (38) to a process watched queue. Current size: 128, max size: 128 -Traceback= 0x60460880 0x614235EC 0x6144F888 0x613C2BF4 0x613EA948 0x613FC8E8 0x6144F9C4 0x6144FC60
Is there a way to manipulate this queue size and avoid such errors.
What is the mechanism that generates these errors.
Thanx in advance.

An internal or external event was dropped because it could not be added to the queue, probably because the queue is full. The result can be minor (retransmission of a SIP message) or major (dropped call), depending on the event that was lost. This error might indicate that the call rate is exceeding the capacity of the gateway. If this is the case, the CPU utilization is excessively high (above 75%). Copy the error message exactly as it appears on the console or in the system log. Issue the show process memory command to gather data that may help identify the nature of the error.

We found the cause but yet to find the solution:
The DNS server was not available during this time.
but another DNS which should have responded is not RFC2782 compliant.
We are using 124-9.T3 on this AS5350, tried to configure it for RFC2052 using sip-ua status -> DNS SRV version 1. Config gets applied but the domain name is still sent with underscores '_'.
For this reason, this DNS server failed to handle requests when the other DNS was not present. Hence the error messages.
