mysql error 28

Hi,

I am getting the following error.

• user warning: Got error 28 from storage engine query: SELECT t.* FROM term_node r INNER JOIN term_data t ON r.tid = t.tid INNER JOIN vocabulary v ON t.vid = v.vid WHERE r.vid = 35 ORDER BY v.weight, t.weight, t.name in /home/anu/drupal-6.10-1/apps/drupal/htdocs/modules/taxonomy/taxonomy.module on line 618.
• user warning: Got error 28 from storage engine query: SELECT DISTINCT b.* FROM blocks b LEFT JOIN blocks_roles r ON b.module = r.module AND b.delta = r.delta WHERE b.theme = ‘bluemarine’ AND b.status = 1 AND (r.rid IN (1) OR r.rid IS NULL) ORDER BY b.region, b.weight, b.module in /home/anu/drupal-6.10-1/apps/drupal/htdocs/modules/block/block.module on line 407.

It occured , when my disk was full (having no free space). But after emptying it and restarting the bitnami server , the error is not going from the website.

When I installed mysql dump in another machine, with drupal stack, there is no error.

As searched in the drupal forums , I have tried to increase the php memory size (http://thanhsiang.org/faqing/node/95), but still unsuccessful in resolving the issue.

Please help .
