Wan connection fails after upgrading to 26.7.3

[sber]

After upgrading to 26.7.3 WAN connection failed on my DEC750, installed hotfixes to 26.7.3_8 but this didn't solve the problem. Serial console shows:

[fib_algo] inet.0 setup_fd_instance: radix4_lockless algo instance setup failed, failures=64
[fib_algo] inet.0 (radix4_lockless#30) rebuild_fd_flm: table rebuild failed
[fib_algo] inet.0 (radix4_lockless#30) rebuild_fd: sync rebuild failed.

Reinstalled 26.7 and imported configuration, system is up and running for now.
