Then I've tried to syncrepl the entire DB, turning on the empty consumers (crazy idea ;) i know ) but the provider memory allocated, again reached 4GB and... bum

some ideas?

4GB is the memory limit on 32-bit Solaris, IIRC. Just like it is 2GB on 32-bit linux. Try building everything 64-bit. Another thing to try, from when I ran my servers on Solaris, is to fix the limits in /etc/system for the maximum amount of memory that can be allocated. I vaguely recall having to do this for my Solaris systems. Oh, and with BDB on Solaris, you want to use the "shm_key" flag in slapd.conf to use shared memory segments, when running on SPARC.

Here's the last portions of /etc/system on my old Solaris LDAP servers:

* turn off executable stacks set noexec_user_stack = 1 set noexec_user_stack_log = 1 * increase the size of the kernel stack to 24k for Solaris 8/64-bit set rpcmod:svc_default_stksize=0x6000 set lwp_default_stksize=0x6000 * force load the shared module kernel information. forceload: sys/shmsys * allow shared memory segments of up to 3 GB (default 1MB) * See http://www.sun.com/sun-on-net/itworld/UIR960101perf.html set shmsys:shminfo_shmmax=3221225472 * Increase memory performance when filesystem is being heavily used. * See http://www.sun.com/sun-on-net/performance/priority_paging.html set priority_paging=1 * Increase memory performance when filesystem is being heavily used. * See http://www.samag.com/documents/s=1323/sam0110e/0110e.htm set maxpgio=25468 set slowscan=500 * autoup influences how much RAM is checked by fsflush every 5 seconds. * Default = 30. Increase autoup to decrease mem management overhead. * See http://docs.sun.com/db/doc/806-7009/6jftnqsin?a=view set autoup = 60 * Up tcp conn hash size. Defaults to 256. * See http://www.deny-all.com/en/solsecu/tech/tuning.html set tcp:tcp_conn_hash_size = 16384 * Up file descriptor limit. Defaults to 1024. set rlim_fd_max = 16384
