TWS 8.4 on HP-UX - lookups?

Just wondering if anyone else is using IBM's TWS on HP-UX 11.11i. Seeing some very strange name-lookup issues when it comes to using various utilities on the system. The same software works fine o0n AIX, Linux, Solaris, etc, but on HP-UX there is noticeable time lags in issuing commands - at the shell level. For example, trying to execute conman type commands, can hang for a minute or more before coming back. if you sniff the net while this is "waiting" you see lots of DNS requests that don't seem to make sense.

This is TWS 8.4 and just wondering if there are others out there using this slightly older release (because of support issues) on HP.

thanks

NAME
ares_gethostbyname_file - Lookup a name in the system's hosts file SYNOPSIS
#include <ares.h> int ares_gethostbyname_file(ares_channel channel, const char *name, int family, struct hostent **host) DESCRIPTION
The ares_gethostbyname_file function performs a host lookup by name against the system's hosts file (or equivalent local hostname data- base). The channel parameter is required, but no asynchronous queries are performed. Instead, the lookup is done via the same mechanism used to perform 'f' lookups (see the lookups options field in ares_init_options(3)). The parameter name gives the hostname as a NUL-termi- nated C string, and family gives the desired type of address for the resulting host entry. The return value indicates whether the query succeeded and, if not, how it failed. It may have any of the following values: ARES_SUCCESS The host lookup completed successfully and host now points to the result (and must be freed with ares_free_hostent(3)). ARES_ENOTFOUND The hostname name was not found. ARES_EFILE There was a file I/O error while performing the lookup. ARES_ENOMEM Memory was exhausted. On successful completion of the query, the pointer pointed to by host points to a struct hostent containing the address of the host returned by the lookup. The user must free the memory pointed to by host when finished with it by calling ares_free_hostent(3). If the lookup did not complete successfully, host will be NULL. AVAILABILITY
