Problems with 8.26.1 upgrade

[vikas027]

We recently upgraded our DigiByte node from version 8.22.2 to 8.26.1, after which we began seeing the following error in the logs:

digibyte-0 digibyte 2025-11-06T03:15:37Z Opened LevelDB successfully
digibyte-0 digibyte 2025-11-06T03:15:37Z Using obfuscation key for /home/digibyte/data/indexes/txindex: 0000000000000000

digibyte-0 digibyte 2025-11-06T03:15:37Z Flushed fee estimates to fee_estimates.dat.

To resolve it, I executed this command:

digibyted -disablewallet -reindex -datadir=/home/digibyte/data

The node stabilized after several hours, but it soon started logging numerous warnings like this:

WARNING: request rejected because http work queue depth exceeded, it can be increased with the -rpcworkqueue= setting

At present, we're performing a complete resync. We've scaled up the CPU and RAM resources and adjusted the configuration from -rpcworkqueue=128 -rpcthreads=16 to -rpcworkqueue=512 -rpcthreads=32, yet the warnings persist.

Anyone else facing the same?

NOTE: I have also logged an issue for the same.
