Re: Memory problem with kannel sms outgoing delivery report
I think the problem is most probably not kannel eating too much memory but MySQL who caches all DB stuff. So consider tuning it.

Re: Memory problem with kannel sms outgoing delivery report
Hi, If it should be kannel issue then I would suggest to try CVS version and if it still crash compile kannel with --with-malloc=check and check logs where memory leaks founds and report it to devel list.

Re: Memory problem with kannel sms outgoing delivery report
Yudi. I use kannel 1.4.1stable in a production environment with vmware, and because this, i had chose to use an sqlbox for storage my DLRs(all types supported, like delivery report to mobile, delivery report to smsc, read report, etc.). With this, despite the kannel CRASHs, the DLRs are recovered from database and the works straight ahead. With sqlbox the leaks are minor, but still there. Like i said on later email, without vmware, the leaks consume the memory, but don't break the bearerbox, despite the performance's down. I think this is a problem in a memory management(more precisely swap management) from VMWare. Finally, if you test the gateway with a vmware(probably a vmware workstation version) in a notebook, be aware that the performance and benchmarks are just approximate(because the performance of notebook, and because the performance of vmware workstation version). I already works benchmarks and crash tests in this way(it's so practical! :) ), but like my production is on a VMWare Server environment, with robust host servers, the difference appears. With my experience, i strongly suggest physical servers for kannel production environments. I test some others SMS gateways, but anyone is so mature and so robust like kannel. + Points to Developers ! Regards. Allison Almeida.

Re: Memory problem with kannel sms outgoing delivery report
I think your issue is maybe that you run out of memory, the kernel stars swapping (- slow) and then crashes at the end. The only reason I can think of is that you use memory based delivery reports instead of mysql based ones and/or that your machine simply doesnt have enough memory to run MySQL and Kannel On 06.11.2007, at 06:23, Yudi Wijaya wrote: can someone here help me.. i have problem with my debian server, i use it for sms gateway use kannel.. well, the problems usually occur when i set delivery report for outgoing sms, then my computer become slow, and harddisk working, after that bash daemon, mysqld, and bearerbox (kannel) is crashed.. i use VMWare with HardDisk 2 GB and memory 320MB.. would you see this error log: http://pastebin.com/m1df0bb68 i got those error on debian screen well, i got no problem with send sms without delivery report Thanks, Yudi Andreas Fink Fink Consulting GmbH Global Networks Schweiz AG BebbiCell AG IceCell ehf --- Tel: +41-61-330 Fax: +41-61-331 Mobile: +41-79-2457333 Address: Clarastrasse 3, 4058 Basel, Switzerland E-Mail: [EMAIL PROTECTED] www.finkconsulting.com www.global-networks.ch www.bebbicell.ch --- ICQ: 8239353 MSN: [EMAIL PROTECTED] AIM: smsrelay Skype: andreasfink Yahoo: finkconsulting SMS: +41792457333

Re: Memory problem with kannel sms outgoing delivery report
One other thing to note is that from those kernel log entries, Kannel isn't crashing per se, it's simply being killed by the OOM-killer (which picks out processes to kill when the machine runs out of memory). From those logs: ... Nov 5 23:03:06 sms kernel: Free swap = 0kB Nov 5 23:03:06 sms kernel: Total swap = 152576kB Nov 5 23:03:06 sms kernel: Free swap:0kB ... 152MB of swap isn't a huge amount, and it's obviously being all used, on top of the 320MB of RAM you have... What does 'top' say just before Kannel is killed? As Andreas said, it's most likely simply that your machine doesn't have enough memory. Solution: add more RAM (adding more swap is just going to kill your performance) Cheers, On 06/11/2007, at 7:11 PM, Andreas Fink wrote: I think your issue is maybe that you run out of memory, the kernel stars swapping (- slow) and then crashes at the end.
