These processing VM's serve up pages to our UI via Hibernate queries. If we disconnect these processing server connections and bounce pgpool, then all of the processing server connections are reestablished with no issues, but if we bounce any one of the processing VM servers while pgpool is up and then try to reconnect, we cannot. The processing servers just hang indefinitely.

Sorry, I'm confused and not sure what operation you did exactly. However,
I see pgpool.conf as below:
# - Pool size -
num_init_children = 32
# Number of pools
# (change requires restart)
max_pool = 4
# Number of connections per pool
# (change requires restart)
By this configuration, pgpool can process only 32 conections, not 128 = 32*4.
The number of preforked pgpool-II server processes. Default is 32.
num_init_children is also the concurrent connections limit to pgpool-II
