UC520 - DNS server error - Low memory

[mike_cynnex]

Has anyone else hit this issue:

006125: Nov  7 12:30:21.132 PST: %DNSSERVER-3-UDPDNSOVERLOAD: Low available memory: dropping <id# 37428> from <cli 192.168..x.x>.

Using a UC520.

Issue seen in following IOS:

uc500-advipservicesk9-mz.151-4.M5

uc500-advipservicesk9-mz.151-4.M4b

No issue with:

uc500-advipservicesk9-mz.151-2.T4

Using the UC520 as a DNS server/forwarder for a small number of hosts < 10 to resolve inside IP's for internal applications.

UC520 will eventually stop resolving DNS requests.

Thanks.

Hi Mike,

What else are you running on the UC520?  VPN, Applications, SSL?  If possible could you post a sanitized version of your config as well?

Thank you,
