Hi Mates,
A fix if done to resolve the crash for classify table in vnet_classify.c
*vnet_classify_new_table*
vec_validate_aligned (t->buckets, nbuckets - 1, CLIB_CACHE_LINE_BYTES);
// oldheap = clib_mem_set_heap (t->mheap);
clib_spinlock_init (&t->writer_lock);
oldheap = clib_mem_set_heap (t->mheap);
clib_mem_set_heap (oldheap);
after this change more than 50k classify tables was able to create without
any crash. But now the crash is observed in creation of classify session ,
not able to create classify sessions for more than 32k table index.
Please share the details like ,how can it be resolved, is there any
additional configurations is needed .
Thanks in advance.
Bt for the crash:
