Maybe this:
set limit option value
   Set various limits on pf's operation.
       * frags - maximum number of entries in the memory pool used
for packet reassembly (scrub rules). Default is 5000.
       * src-nodes - maximum number of entries in the memory pool
used for tracking source IP addresses (generated by the sticky-address
and source-track options). Default is 10000.
       * states - maximum number of entries in the memory pool used
for state table entries (filter rules that specify keep state).
Default is 10000.

or this:
set timeout option value
   Set various timeouts (in seconds).
       * interval - seconds between purges of expired states and
packet fragments. The default is 10.
       * frag - seconds before an unassembled fragment is expired.
The default is 30.
       * src.track - seconds to keep a source tracking entry in
memory after the last state expires. The default is 0 (zero).

Try change this options.
