Bad Decompression error after default ssl_session_timeout

I have an LB setup with nginx for an ssl enabled site which load balance
with 2 apache servers. All the servers are CentOS5.5* and  OpenSSL
0.9.8e-fips-rhel5 01 Jul 2008. Also we are using the same SSL
certificate on all the 3 servers.

It does load balance perfectly untill 5m. After that it raises an

[crit] 5179#0: *6 SSL_do_handshake() failed (SSL: error:1408F06B:SSL
routines:SSL3_GET_RECORD:bad decompression) while SSL handshaking to
upstream, client: clientip, server:, request: "GET /search/
HTTP/1.1", upstream: "https://server1-ip:443/search/", host:

This error happens for both server1 and server2. After this, the load
balancer is not working.

The following are the nginx conf.

http {
    include       mime.types;
    default_type  application/octet-stream;
    autoindex off;
    ssi off;
    server_tokens off;

    log_format  main  '$remote_addr [$time_local] - "$request" - '
                      '$status - $body_bytes_sent - "$http_referer"';

    log_format load_b '$remote_addr [$time_local] - "$request" - $status

                      'worker_status $upstream_status - '

                      'total_processing_time $request_time - '

location / {
           proxy_pass https://loadbalancer;
           access_log logs/access_lb.log load_b;

        error_page  403 templates/403.html;
        error_page  404 templates/404.html;
        error_page   500 502 503 504  /50x.html;

        location = /50x.html {
            alias templates/500.html;

What can be the issue? Thanks in advance.
