Reset Connection count Skyline Maestro

David_Evans — Mon, 08 Sep 2025 18:45:04 GMT

This has been an occasional issue for several years even on SNMP monitoring, but lately, my Skyline Maestro boxes are doing this quite regularly. The TCP concurrent connections are maxing out at some very large bit boundary and staying there until I reboot.... or mess with the interfaces in some other way. I found all the threads on how (not) to reset the RX TX errors on the NIC's but my searching didn't find anything on the more checkpoint counters like TCP handshake.

Is there a non intrusive way to reset these?

I am impressed with the throughput on these boxes but I think that thirty-six quintillion eight hundred sixty-seven quadrillion nine hundred three trillion two hundred four billion one hundred sixty-nine million nine hundred sixteen thousand concurrent connections is a little beyond their capabilities.

This is a known issue, which is not yet completely solved, but there are alredy fixes available that are solving this issue for most cases. I have an open SR for this.

Ask for PRHF-29330, PRHF-34777, PRHF-39669 and PRHF-40998. The last two ones are SP only the rest is for SP and Non-SP
