Corrupt table

Hi,

We have a log table that is notoriously getting corrupt.

The usage is to log all web requests, and in an batch job aggregate those requests and delete the aggregated rows.

Approx rows pr day is 400000 (during holliday...).

The table is defined as:

CREATE TABLE wisweb.DBA.Log (

  Id int NOT NULL,

  Time timestamp NULL,

  Servlet char(100) NULL,

  Params text NULL,

  Type int NOT NULL,

  TableName char(50) NULL,

  IdFieldName char(50) NULL,

  IdFieldValue int NULL,

  Referer text NULL,

  SearchString char(100) NULL,

  RecordCount int NOT NULL,

  Url text NULL,

  TableId int NOT NULL,

  ServletId int NOT NULL,

  IP varchar(50) NULL,

  UserAgent varchar(200) NULL

);

-- Creating indexes

CREATE INDEX "Time" ON Log ( "Time" ASC );

CREATE INDEX "Type" ON Log ( "Type" ASC );

CREATE INDEX "IdFieldValue" ON Log ( "IdFieldValue" ASC );

CREATE INDEX "RecordCount" ON Log ( "RecordCount" ASC );

CREATE INDEX "TableId" ON Log ( "TableId" ASC );

CREATE INDEX "ServletId" ON Log ( "ServletId" ASC );

CREATE INDEX "IdFieldName" ON Log ( "IdFieldName" ASC );

And when I validate the table I get:

Validate table log;

ERROR: Row count mismatch between table "Log" and index "Time"

SQL Anywhere Error -300: Run time SQL error -- Validation of table "Log" has failed

And the corresponding:

Validate index "Time" on Log;

Fails with the same error:(

I can rebuild the Time index without problem, but it still will not validate.

I can even drop the index and recreate it and it still fails validation!

And if I validate the table without the Time index, it fails on the IdFieldValue index.

Last time I had to rename table, create a new one and copy data over to the new table. But I only stayed uncorrupt for about two weeks:(

We are running the version:

dbsrv12 GA 12 0 1 3967 linux 2013/09/04 15:54:03 posix 64 production

Best regards
