[otrs] Huge data to encode in JSON cuase Apache 500

Hi all, I've setup an OTRS (version 3.1.21) on a 3GB / 2 CPU virtual machine. I have made a CGI to return a ticket list into JSON. For this, I use the method TicketSearch. There, I have a hge hash to output as JSON. ************************ use JSON; print "application/json"; print JSON->new->encode($Result); ************************ This encoding cause a 500. I have <:Apache2 IO write: (103) Software caused connection abort> in apache logs. Is this a memory problem ? How could I solve it ? Regards,
